frouisfrr.,LEArnj'or Losaiientnis i To @ZZ whom, it may concern: i 3 Be it known that I, Louis K. LEAHY, a

citizen of the United States of America, re-

siding at LosjAngeles, in the county of Los Angeles, State' of'California, have invented -certaln new and useful Improvements in Hydrocarbon-Burning Apparatus, of nwhich the following is aI specification.

' This invention relates to means for atomizing andl burning hydrocarbon oils, and particularly toy a xparatus for utilizing as fuel the iiuln oils `of California, and has for-its objectthe'provision of exceedingly simple, durable, positive, and eflicient means for atomizing the heavy oils with a blast of steam or compressed air and in the provision `of means for readily'coupling th'e atonnZing head ortip with thesteam and oil supplypipesand'providing means whereby steam maybe 'turned into the oil-pipe to thoroughly clean the same, as well as the oilways and discharge-`slots of the atomizing'head or tip.

the or supplypipe l5, communicating with Thisway 6 is open into the oil-pipe 7, screwedinto the wall 6 ofthe coupling 3, as shown', the pipe 7 being within a steam-pipe 8, which is inserted into the opening ofthe way 4. A collar 9 is provided with a ysuitable thread, so`

that it may be turned up against the end wall 9 of th'eway 4, and a locking-collar 10 is provided of a suitable diameter to engage theveXternal threads 11,*and thislocling-collar'l'O is provided with a liange 12, adapted to bearagainst edge ofthe collar 9, the center if-theflange'12 being cut away to allowthe,

A portl 13 is provideth'leading from the way 4 into the way 6, thus l forming a by-pass for the. steam, so that thelist'earn may beA turned into the oilway to 'clearfthe same. This port 13 is controlled'by a Vsuitable valve 14, the stem of the valve passing f through stuffing-boxes 15 16, as shown.

17 represents the tip-casing, provided with a shank 17', adapted to receive theend of the pipe 8, as shown, a steamwaylS being formed in the lower portion of the casing y17,713; and in communication with the pipe 8. The;

central portion of the tip or casing 17 is provided wi'th a threaded opening adapted to receive the end of the oil-pipe 8 and with an oilway 19 leading into the hollow chamber of the casing. As shown, this casing 17 is provided with a hollow central chamber operi/"l at its upper end. This chamber vis prefer ably cylindrical in form and has a closed bottom, as shown.

rl'he front wall of the two portions or sections 20 21, terminating some distance from one another and forming a wide slot between the edges of the sections 2O 21. As shown, the inner surface of the section 2() is arranged outside the outer surface of the section 21-, being so spaced to form a downwardly-extending way external of the outer surface of the lower portion of the tip.

22 represents a hollow plug which is adapted to be inserted into the cylindrical chamcasing 17 is formed in ber of the casing 17. This plu@ is preferably provided with a threaded shan r 23, adaptedv to screw through a threaded opening in theI bottom of the casing 17 and preferably lof sufiicientlength ,to project below-the outer IOO surface of the' ybottoml to receivea lock or jam nut 24.` Preferably the plug is also provided with a second shank 25, which is".v`

threaded to receive the cap 26 'Iheplug 22j has a cent-ral `oil way or-chamber 26 leading diametrically therethrough and adapted'tos register with the way 19.

Preferably -thei under sideor lower face of the plug 22 is ree",` cessed, as shown, to form a stema-expansionl l ,-.cliamher and an yannular channel 27 formed;

. 'steam projected will be of greater width thanA xo therwidth of the oil-sheet. It is. thus seen that-the oil-discharge duct 30, `formed between the inner 'surface of the wall or section 205'and the outer surface of the plug 2v2, dischar' es downwardly and right angularly to thfep ane of discharge of the'steam-discharge slot 31 formed lbetween theup er edge of the ring 28 and the under side of t e plu 22, so thatthe oil is projected into the s eet of steam, whichexpanding u wardly commin- 'zqgges withthe oil, thoroug ly atomizing it.

y'providin an annular channel or groove 217 in the un er side or lower face of the plug 22, andthus forming an abutment for the steam to strike against, the steam is preventz 5 ed from rushing directly out the dischargeslot 31',5 the steam cushioning against t eabutment, breaking up the steam, and elfectuating a more thorough atomization of the oil. l y
